What do these codes mean?

My service engine soon light came on today. I went to Advance Auto to pull the codes.

p1150 Manfacurer Contrl.
Fueil Air Metering

p0171
System to Lean
(Bank 1)

p0174
System to LeaN
( bANK 2)

Any help on whatthese mean and suggestions on fixes would be greatly appreciated. I have an 02 gt covertible with no mods except for flowmasters
Thanks

When did the codes first pop up? I.e. were you putzing with anything beforehand, or did you notice any difference in the way the car behaved when it came on?

Check for vacuum leaks first then check the mass air sensor wire for oil/dirt buildup. if the mass air is dirty try cleaning it with some electrical cleaner clear the faults and see if the problems remain.
